NestJs Dynamic Module Inside Service (Runtime)

Question

I am looking at how I can import modules in NestJs runtime based on some logic in the service.

What I am trying to achieve is to build a "plugin" system which uses whichever modules are installed to extend a base service for example, if I have an FxModule which job is to return exchange rates

I might like to "extend" this module with different providers, e.g. XE or Oanda for different client applications based on which one is installed. So something like:

FxService
   -> XE (if module installed)
   -> Oanda (if module installed)

I have the function which checks if the modules are installed but I am struggling to get my FxService to import and use the module in runtime.

I am looking to do something like:

let fxModule: any

if (utils.Modules.isInstalled('@something/xe')) {
    fxModule = require('@something/xe')
    fxModule.register()

    const result = await fxModule.someService.someFunctionEgGetRate()
}

This module will be pulled in via NPM, so it's just how I can do this "in the NestJS way" otherwise, I guess I move to Vanilla Typescript and drop the NestJs dependancy.
